摘 要
在当今的船上，船舶制冷装置是冷藏船、液化气船、船舶伙食冷库、冷藏集装箱和船舶中央空调系统的核心设备。伴随着海运业迅速发展和制冷、空调装置的广泛使用，在制冷装置操作管理中正确分析、判断并迅速排除故障已成为轮机管理人员的重要职责。制冷装置各部件设计制造不妥，或操作管理不当均可能造成相关运动部件和自控元件频繁出现故障。故障一旦产生，船舶管理人员就应及时分析故障诱发因素，并快速、准确地找出故障源进而加以排除。因此，对船用制冷装置的故障诊断与处理对轮机员来说是一项具有挑战性的工作。此文分析了船舶制冷装置的常见故障，并从设计和管理两方面阐明了各种常见故障的诊断方法，并着重从船舶制冷操作管理角度提出了排除各种故障的相应的对策。

ABSTRACT
In today's on board, ship cooling device is a refrigeration ships, liquefied gas vessels, ship food cold storage, refrigerated containers and ship the core of central air-conditioning system equipment. Along with the rapid development of the maritime industry and refrigeration, air-conditioning device widely used in refrigeration equipment in proper operation and management analysis, troubleshooting to determine and quickly has become an important engine management functions. Refrigeration equipment design and manufacture of various components is wrong, or the operation may be caused by mismanagement related to moving parts and frequent failure of self-control components. Fault once, ship managers should be timely analysis of fault-induced factors, and quickly and accurately identify the fault source to be excluded. Therefore, marine refrigeration equipment fault diagnosis and treatment of the engineer is a challenging task. This article analyzes the common ship refrigeration device failure, and from the design and management of two common failure to clarify a variety of diagnostic methods and focus on operations management from the perspective of the ship refrigeration has removed all kinds of faults corresponding countermeasures.
